Here my setup, 1 room 2 set speakers (depend what music i want to listen)
Auralic Altair RCA to in Mystery Pre and out to Mono to VR4Jr. Second pre out to B&W sub( I think this setup good)
I connected another XLR out put from Auralic direct to Halo A21 to Opera Seconda . I do not like the sound without pre amp. That why i am thinking to disconnect second pre out to sub and connect to Halo, use Halo loop to B&W sub. Because i don't think VR4jr need sub. Please help! Thanks for all advice
Merry Christmas to everyone
